You laid down on the ground after a rough defeat. During the extermination you had been brutally attacked and you could've died...there was a giant gash on your chest running from your shoulder to your waist. You laid bleeding out on the ground.

You noticed footsteps approaching. He stood and just looked at you, he didn't like you one bit, you were enemies but now you were desperate for his help. Would he help? Well you'd need to convince him and he wasn't easily swayed.

He could tell just by your expression that you were desperate. And he just looked, annoyed. He didn't enjoy seeing you in pain, he wasn't a sadist and he wasn't anything like Alastor, but still. He was angry at you for just generally being your enemy.
